How to create correct Tree folders and files

If you have many many methods in one controller ex. articles you should build folder according on the modules

You do not have to have big applicaiton to create tree. Example in articles modules you should have folder tree looks like

-app
    -Controller
        -Articles // Controller folder
            -Content.php
            -Category.php
        -Controller.php
        
    -Model
        -Articles // Model folder
            -Content.php
            -Category.php
            -Commnets.php

For comments you don't have to Controller becouse comments will be under article so you should load

$this->loadModel('Articles/Commnets');

in your Articles/Content

Router

will be looks this

index.php?taks=articles,content&action=index
index.php?taks=articles,category&action=index

or Friendly Url

articles,content/index
articles,category/index
